The arm bones are called the humerus, radius, and ulna. The humerus is the long bone in the upper arm, while the radius and ulna are located in the forearm. The radius is on the thumb side of the forearm, and the ulna is on the pinky side.
- The humerus connects to the shoulder blade at the shoulder joint and to the radius and ulna at the elbow.
- The radius and ulna work together to allow for a wide range of motion in the forearm, including rotation, extension, and flexion.
These three bones are crucial for the movement and stability of the arm, allowing us to perform a variety of tasks using our hands.
